Closed Cell Polyethylene Foam
Durable, custom-engineered foam solutions for high-performance applications
At Kewell Converters, we’ve spent over 50 years mastering the craft of foam conversion. Based in Kent, we specialise in high-quality bespoke foam solutions that perform in the most demanding environments.
Our experience with closed cell polyethylene foam enables us to design and manufacture highly customised foam parts and components that are lightweight, durable, chemically resistant, and offer excellent energy absorption—ideal for protective, structural, or transit-critical applications.
Why choose closed cell polyethylene foam?
Closed cell polyethylene foam offers a range of performance benefits that make it ideal for technical applications.
Whether you need custom foam inserts, technical gaskets, precision panels or intricate foam shapes, Kewell Converters can specify, source, convert and supply the right polyethylene foam to meet your exact requirements.

Cross-Linked Polyethylene Foam (XLPE)
High-performance foams offering exceptional durability and precision. We fabricate and convert:
- PLASTAZOTE® – closed-cell LDPE/HDPE foams, customisable and durable with flame-retardant and anti-static options
- EVAZOTE® – closed-cell EVA foams, ideal for sports, aerospace and medical applications
- SUPAZOTE® – EMA copolymer-based foams for highly specialised needs
These foams come in densities from 15kg/m³ to 120kg/m³ and a variety of colours. They’re commonly used for foam inserts, transit protection, aerospace panels, military-grade packaging and more.
We also offer PALZIV’s PalFoam and GalFoam—cost-effective, versatile alternatives available in block and roll forms.
Non-cross-linked polyethylene foam (PE)
Lightweight and recyclable, this foam is a go-to choice for blocking, bracing, surface protection and packaging. Available in anti-static grades and custom thicknesses, it’s ideal for cost-conscious applications where performance still matters.
We supply industry-leading brands such as:
- Ethafoam® Plank
- Stratocell® Laminated Plank
- Nopa Plank®
- Polylam®
Common uses of polyethylene foam
Polyethylene foam is incredibly versatile and widely used across multiple sectors for its durability, water resistance, and shock-absorbing properties.
We use advanced fabrication methods like CNC routing, lamination, and waterjet cutting to deliver precision-engineered foam parts tailored to your needs.
Vibration and shock dampening
In transit and industrial environments
Buoyancy blocks and marine floats
Lightweight and water-resistant
Custom gaskets and seals
Chemically resistant and easy to shape
Orthotic supports and medical padding
Hygienic, soft, and skin-friendly
Tool control and drawer inserts
For organisation and damage prevention
One supplier. One seamless process.
Kewell Converters is more than just a foam converter. We’re increasingly managing the full supply chain—from sourcing materials to delivering ready-to-install parts. That means fewer suppliers for you to deal with, faster lead times, and more confidence in your final product.
Let us help you streamline your next project with smart, dependable foam solutions.
